Given, `2Fe_2O_(3(s)) to 4Fe_((s)) + 3 O_(2(g)), Delta_r G_1^@ = +1487kJmol^(-1)` `6CO_((g)) +3O_(2(g)) to 6CO_(2(g)), Delta_r G_2^@ = 1543.2kJmol^(-1)` Select the correct statements:A. `Delta_(r)G^(@)` for reduction of iron oxide by `CO` is `-56.2 k J m^(-1)`B. `Fe_(2)O_(3)` cannot be reduced by `CO` spontaneouslyC. `Fe_(2)O_(3)` can be reduced by `CO` spontaneouslyD. The reduction of `Fe_(2)O_(3)` takes part in higher part of blast furnace |

Answer» Correct Answer - A::B::D `Delta_(r)G^(@) for 2Fe_(2)O_(3)+6COto4Fe+6CO_(2)` `Delta_(r)G^(@)=Delta_(r)G_(1)^(@)+Delta_(r)G_(2)^(@)=+1487-1543.2=-56.2 kJ mol^(-1)` |
